Hajime no Ippo began as George Morikawa's boxing manga in 1989 and was adapted into a TV anime in 2000. Shocking Lemon performed Inner Light as the show's second opening theme, and its bright rock sound became closely tied to Ippo Makunouchi's growth as a featherweight boxer. Short cuts now circulate in training edits and anime soundboards, much like Giorno's Theme is used to give a scene instant drama. The track remains popular because it signals determination without needing dialogue or a long build-up.
